According to Radio.com, Ghanaian youth activist Jonathan Osei-Owusu claims that Brown "promoted an illegality". He continued: "You can see from the video, and yet he was let go free."

After Brown's March 6 appearance, Osei-Owusu started a campaign and petition to see the US artist and boyfriend of Rihanna face trial for promoting smoking marijuana while in a stadium full of young fans.

The statement reads: "He is on video to have encouraged the audience to take up arms against people who stand in their way to smoking weed. In our prisons, many are incarcerated for [the] same."

Osei-Owusu also claims to have been present at the gig. He added: "When you live in the city or the village, you understand the smell of marijuana. I was there. We smelled weed. That is what he promoted."

He continued: "The last two days, I have been with the police and an investigation has commenced. The police have moved swiftly and they are not leaving anything unturned."

The event's organisers have allegedly denied that Brown was smoking weed on stage, branding the incident a stunt.
